Americans spent an average of $13,493 per person on healthcare in 2022, according to CMS.gov. When those costs pile up, the tax code offers a way to recoup some of the financial burden. What is a tax deduction for healthcare, and how can it put money back in your pocket? If your medical expenses were significant last year, this question is worth answering carefully.
A tax deduction reduces your taxable income, which in turn lowers the amount of federal income tax you owe. What is a tax deduction in practical terms? It is the government’s way of acknowledging that certain expenses, including medical costs, should not be taxed as income. This guide explains how healthcare-related tax deductions work, what qualifies, and how to claim them.
Tax Deductions: The Basic Mechanism
A tax deduction subtracts a specific amount from your gross income before the IRS calculates your tax liability. If you earn $75,000 and claim $5,000 in deductions, you are taxed on $70,000 instead. At a 22 percent tax bracket, that $5,000 deduction saves you $1,100 in taxes.
Tax deductions are different from tax credits. A deduction reduces your taxable income. A credit directly reduces the tax you owe, dollar for dollar. Deductions are valuable, but credits are generally more powerful. For healthcare expenses, deductions are the primary mechanism available to most taxpayers.
The Medical Expense Tax Deduction
The IRS allows you to deduct unreimbursed medical and dental expenses that exceed 7.5 percent of your adjusted gross income (AGI). This threshold means that only expenses above that floor count as a deduction.
Here is how it works. Your AGI is $60,000. Seven and a half percent of $60,000 is $4,500. If your total unreimbursed medical expenses for the year were $8,000, you can deduct $3,500 (the amount exceeding $4,500). At a 22 percent tax rate, that deduction saves you $770.
To claim this deduction, you must itemize deductions on Schedule A of your federal tax return rather than taking the standard deduction. For 2025, the standard deduction is $15,000 for single filers and $30,000 for married couples filing jointly. You benefit from itemizing only if your total itemized deductions exceed the standard deduction amount.
What Medical Expenses Qualify
The IRS defines qualifying medical expenses broadly. They include payments for diagnosis, treatment, prevention, and cure of disease, as well as costs for equipment and supplies needed for these purposes. Qualifying expenses include insurance premiums you pay with after-tax dollars, prescription medications, doctor and specialist visits, hospital stays and surgeries, dental and vision care, mental health services, physical therapy, medical devices like crutches and wheelchairs, and transportation to medical appointments.
Cosmetic procedures generally do not qualify unless they are medically necessary due to injury or disease. Over-the-counter medications without a prescription do not qualify. Health club memberships are excluded even if exercise is recommended by a doctor.
Health Insurance Premiums as Tax Deductions
If you pay health insurance premiums with after-tax income, those premiums may qualify for the medical expense deduction. This applies to marketplace plan premiums not offset by premium tax credits, COBRA premiums, Medicare premiums (Parts B, C, and D), supplemental insurance premiums, and long-term care insurance premiums up to age-based limits.
However, if your employer pays your premiums or if they are deducted pre-tax from your paycheck, those amounts do not qualify. They have already received tax-favorable treatment. Self-employed individuals can deduct health insurance premiums directly on their tax return without needing to itemize, using a separate line item on Form 1040.
HSA and FSA: Tax-Advantaged Alternatives
While the medical expense deduction requires itemizing and clearing the 7.5 percent AGI floor, Health Savings Accounts (HSAs) and Flexible Spending Accounts (FSAs) offer tax benefits without those hurdles.
HSA contributions are tax-deductible or pre-tax if made through payroll. Withdrawals for qualified medical expenses are tax-free. For 2025, contribution limits are $4,300 for individual coverage and $8,550 for family coverage. FSA contributions are also pre-tax, reducing your taxable income dollar for dollar, with a 2025 limit of $3,300.
These accounts can be more beneficial than the medical expense deduction for many taxpayers, especially those who do not have enough total itemized deductions to surpass the standard deduction threshold.
Tax Deduction vs. Insurance Deductible
The word “deductible” appears in both tax and insurance contexts, but the meanings are completely different. A tax deduction reduces your taxable income. An insurance deductible is the amount you pay for covered services before your insurer shares costs. They are unrelated mechanisms.
However, there is an indirect connection. The money you spend on your insurance deductible, along with coinsurance and copays, counts as unreimbursed medical expenses. If those expenses exceed 7.5 percent of your AGI, the excess may be tax-deductible. So your insurance deductible payments can potentially become part of your tax deduction.
How to Claim the Medical Expense Deduction
To claim healthcare-related tax deductions, follow these steps. First, track all unreimbursed medical expenses throughout the year. Keep receipts, Explanation of Benefits statements, and records of mileage driven to medical appointments. Second, add up all qualifying expenses at year-end. Third, subtract 7.5 percent of your AGI. Fourth, compare the result to your standard deduction along with other itemized deductions. If itemizing produces a larger deduction, file Schedule A with your tax return.
Tax software and professional tax preparers can automate this comparison. If you had a year with unusually high medical expenses, such as a major surgery, extended hospital stay, or expensive ongoing treatment, itemizing may be worthwhile even if it typically is not.
Frequently Asked Questions
What is a tax deduction for healthcare?
A healthcare tax deduction allows you to subtract qualifying unreimbursed medical expenses from your taxable income. You can deduct the portion of these expenses that exceeds 7.5 percent of your adjusted gross income. This reduces your tax bill but requires you to itemize deductions on Schedule A.
Can I deduct health insurance premiums on my taxes?
You can deduct premiums you pay with after-tax dollars, including marketplace premiums, COBRA, and Medicare premiums. Premiums paid pre-tax through your employer do not qualify since they already receive a tax benefit. Self-employed individuals can deduct premiums directly without itemizing.
What is the 7.5 percent rule for medical deductions?
The IRS allows you to deduct only the portion of unreimbursed medical expenses that exceeds 7.5 percent of your adjusted gross income. If your AGI is $80,000, only medical expenses above $6,000 are deductible. Expenses below that threshold cannot be deducted.
Is it worth itemizing for medical expenses?
It depends on your total itemized deductions. If your medical expenses plus other deductions like mortgage interest, state taxes, and charitable contributions exceed the standard deduction ($15,000 single, $30,000 married filing jointly for 2025), itemizing saves you money. Otherwise, the standard deduction provides a larger benefit.
Can I deduct dental and vision expenses?
Yes. Dental and vision expenses are eligible for the medical expense deduction. This includes cleanings, fillings, crowns, eye exams, prescription glasses, and contact lenses. Cosmetic dental procedures like teeth whitening generally do not qualify.
